G.. S. RIDER DIRECTORY BOARD FOR OFFICE BUILDINGS Filed Feb. 7, 1930 2 Sheets-Sheet 2 Cil corners at one side the inner leaf is hinged to the outer leaf by hinge members 2O cooperating with lugs 21 mounted on or integral with one of the. frame strips of theV outer leaf. Normally the two leaves are held together, or in vclosed position as inrFig. 2, by swing clips 22 pivotallyinounted on lugs 23 extendingfrom the side member of frame 15 rearward from the hinged side of the pan'l'i. h' l I Y To detachably retain the exhibit cards, here represented as narrowA cardboard directory slips 24, the side members ofthe 'inner leafV portion of this compressible stripmprojects substantially beyond the side flanges oftie channel strip 28, and its outer face is slightly forward of the normal flat plane of the directory slips, so vthat after inserting the ends of the slips in the channels in an obvious way n they have slight resilient bearing against the outerface ofthe cushion strip and are thus temporarily retained' in desired; positions,

and then when all adjustments are made for. Y

anyfpaneland the leaves thereof areclosed andg secured, (Fig. 3) the cushion strip 291s compressed and'squeezes the central portions of all ther directory slips with substantial force againstl the coverglass 16 so that 'accioutward. Each offthese lugs has a verticalbore or pin socket 31 (see Fig. 4). The upper socket is engaged by a hinge pin 32 hav-V inge head 33 mounted in. a'sleeve 34 which islocated in a channel formation of the main frame between the upper panel 5 and the horizontal frame strip 10. The hinge pin passes through a hole4 in strip 10 registering with holeor socket 31 when the panel is in position. vIn' sleeve 34 is a spring' urging the hinge pin downwardto engage in hole 31. At the bottom of the panel, the pin hole or socket` 3,1 in the Vbottom lug 3() may be en-A gaged byga :fixed hinge pinheld in a lug 36 on'the mainframe. f A

The panel being in position as shown, to remove it, it is only' necessary to insert a small rod-like implement such as ay nail upward through'the hinge hole 31, thus forcing the hinge pin 32 back into its socket and out of the hole. Thereupon the panel may be swung forward sufiiciently to clear the frame, and the lower hinge connection is disconnected merely by lifting the panel slightly. The panel may bereinserted by reverse operations vas easily understood. By this arran ement unauthorized persons will not rea ily perceive or understand the mode of i' mounting of the panel and unauthorized removal is practically prevented, whereas if ordinary hinge structures, or ordinary manipulable devices such as screws or nuts were employed, the mode of removal would be relatively obvious; and at the same time the exposed hinge formations are limited to the relatively small lugs 30, and the decorative appearance of the structure is'not impaired.

yI also provide suitable means at the free.y

edge of the'panel for locking it in closed position. Such means may consist of .a keyedY lock, or preferably a keyless lock of the charg acter` disclosed in a companion `application Serial No. 426,475, filed Febp?, 1980, and sufficiently represented here by the keyhole 40 and latches 41 cooperating with upper and lower horizontal main frame strips 50. Details of this lock or latch and operating arrangement are not claimed herein.

Itvis desiredjtosavoid placing any handl orJknob/on the outer face of the panel, in orderV to discourage-theV idea that it Vmay be opened. "To facilitate the opening of the panel by authorized persons in the absence of a knob or handle, frame strip 51 is provided in aposition corresponding to the side member of eachpanel, at its free side,iwith an'outwardly acting spring device, consisting 'as hereshown of a'vertically directed latfor stripy spring 55 of sheet metal, riveted at its centerto strip 51. 1 i" f The spring` is normally bowedas shown in Fig. 3, and hasfreversely-curvedends 56 toV slidably engagethe panel side member.

Vhen the panel is shut and latched the spring l is iiattened and stressed as shown inv Fig. 2, and when the panel is unlocked the spring willrimmediately throw the free edge of the paneloutward sufficiently to permit grasping and further manipulation The projecting lugs 30 provide an 'offset hinge mounting for the panel, so that when a plurality of panels are mounted in the main frame as shown in Figs. 1 and elsewhere, the panels are all aligned, the free edge of one panel abuts against the hinged edgeof the next, and when any panel is swung out as suiiiciently shownin Fig. 3, it may be folded flat, against the outer faces of the other panels, which do not interfere 'with this hinge action.'` The inner'rleaf of the, panel may then be unlat'ched as above referred to, and swung out to any convenient position, or flat against the face Iof an adjacent panelor the l. An exhibiting structure of the character described, comprising a main frame having a panel aperture, and a panel hingedly mounted therein, the panel having outwardly o-Hset hinge members whereby it may be swung out through a half rotation and positioned in a plane slightly forward of the general outer plane of the main frame, said panel hinge members being located at the top and bottom of the panel respectively and within the limits of upper and lower members of the main frame, and cooperating hinge members on said main frame members and engaging in the panel hinge mmebers.

2. An exhibiting structure of the character described, comprising a main frame having a panel aperture, and a plurality of independent panels hingedly mounted therein in plane alignment when closed, each panel having its hinged side in close abutting relation to the free side of an adjacent panel, and the panel hinge member being outwardly offset to provide for substantially full half rotation without coniict with other panels or the frame.

3. An exhibiting structure of the character described, comprising a main frame having a panel aperture, an exhibiting panel havingy outwardly projecting hinge lugs, one of the lugs having a vertical hole extending therethrough, and a hinge pin reciprocably mounted in the frame and entering the lug hole which is accessible by the projecting position of the hinge lug for insertion of a rod like implement through the hole to push back the hinge pin and release the panel for detachment from the frame.
